Coil Winder PCB
This PCB is used to populate the necessary electronics for my custom coil winder circuit. The circuit is built around an STM32F401-based microcontroller. The user has two buttons and a rotary encoder with a switch to navigate in the menu displayed on a Nokia 5110 LCD. The two stepper motors (feeder and main shaft) are driven by a DRV8825 stepper motor driver. The PCB also has a LD33V voltage regulator that converts the input voltage to 3.3 V which then powers the microcontroller, the display, the buttons and the rotary encoder.
This PCB and the software I provide on my website allows anyone to build their own coil winder based on two stepper motors. The already prepared PCB helps us to get rid of a serious amount of wires and the code I wrote makes it possible to anyone without any programming knowledge to automatically wind their own coils.
Important components
- C1 and C2 are 100 uF 50 V electrolytic capacitors
- R1 and R2 are 10k resistors
- C3 is a 100 nF ceramic capacitor
- U1 is a LD33V 3.3 V voltage regulator
- C4 is a 10 uF 50 V capacitor
- The switches are 12 mm
